XPInstantFeedbackView Class

A data source that binds DevExpress grid controls with data tables and allows retrieving data from the server side in InstantFeedback mode.

Namespace: DevExpress.Xpo

Assembly: DevExpress.Xpo.v22.1.dll

Declaration

public class XPInstantFeedbackView :
    Component,
    IListSource,
    IXPClassInfoProvider,
    IXPDictionaryProvider,
    IDXCloneable

Remarks

Use the XPInstantFeedbackView component to work with DevExpress grid controls in instant feedback mode. The component combines the advantages and features of XPInstantFeedbackSource and XPView.

The XPInstantFeedbackView is a read-only data source. To enable data editing in server mode, use the XPServerCollectionSource with the XPServerCollectionSource.AllowEdit property set to true.

XPInstantFeedbackView ships with the following capabilities:

  • Ability to handle large data sources with lower memory usage (does not load an entire persistent object instance).
  • Ability to customize SELECT statements to exclude unused data columns.
  • Ability to include reference property data (nested properties) in the root query to avoid the 1+N problem.
  • Ability to include custom (virtual) properties calculated on the server side (similar to ServerViewProperty).
